Standards Development
This document applies to signalling and telecommunication apparatus (including power supply system belonging to signalling and telecommunication apparatus) that is installed inside interlocking locations, wayside cabinets and other wayside locations including platforms (including vital equipment such as interlocking, signals, point machines, level crossing, etc.).
This document specifies limits for emission and immunity and provides performance criteria.
The standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to this set of apparatus when operating under normal conditions. Fault conditions of the apparatus have not been taken into account.
The test frequency range defined in this document is considered to ensure the electromagnetic compatibility of the apparatus in the whole frequency range from 0 Hz (DC) to 400 GHz.
